Annapurna makes a guess on the finished lens thickness. This is needed when deciding whether to use a d finished lens or surface/buy-in lens for the order.
The guess may not be accurate for some lenses so to overcome this, a method of specifying the thickness(subs) for the finished lenses has been added.
A new file has been added which will allow the thickness to be set for each diameter. It is a CSV file.
The first column contains the lenscode+diameter.
The remaining columns contain the thickness for the powers as indicated in the title row.
An example file can be downloaded from here: finsubs.csv and placed in the masterdata folder.
The file can be amended from the lens data update screen.
